Structural Optimization for Wall Frame Design of a Forging Manipulator

摘要

The optimization designs are performed to the structural wall frame of the forging manipulator. The stress conditions of the wall frame are obtained based on the results of the dynamic analysis of the forging manipulator under the multiple load cases. The topology optimization and sizing optimization are carried out to the classic types of heavy-load manipulators. The global stiffness of the wall frame is maximized subject to the volume constraint for the topology optimization; and the sizing optimizations, in which the objective is the minimizing the maximum displacements with the different design variables, is carried out under the mass constraint and the maximum Mises stress constraints. Results show the improvement of the performance of the wall frame in the forging manipulator.
